IMPROVEMENT IN PUMPS.

Tht: Schedule referred to in these LettersPatent and making part Ofthesame.

To all lwhom. fit may concern Beit known that I, R. W. Cnousn, ofWestminster, in the county of Carroll, and State of Maryland, haveinvented a new and improved Pump; and I do herebyideclare that thefollowing is a full, clear, and exact description of the constructionand operation of the saine, reference'being .had to the accompanyingdrawings, making a part oi' this specification, in which lmy inventionis represented by a side view, a portion oi' the wall being broken away.

The. object of this invention is to provide forpublic use adouble-acting pump, so constructed that it can be conveniently repairedwhen the packing 'becomes worn or injured.

,ln the drawings- A represents the upper chamber, and v B', the twocylinders connected with it, there being ltwo valves, not shown, betweentbe upper ends of the cylinders and the lower side of chamber A.

rlhc plunger-s are worked Vat the lower end of the two 4cylinders bymeans of rods or straps G C', extendingdowny alongside of or around the`cylinders from a double-crank shaft, l).

The rot-ation of the shaft gives an alternate reciprocating action tothe rods and plungers, as will be at once understood ii'om the drawings,thereby forcing the water up through the cylinders into chamber A, andthence discharging it through the pipe E.

The plunger consists of a disk,`M, fitting into the lower end of thecylinder, and havingan opening, an, through its centre.

.A curved brace-yoke, n, is suitably attached to the under side of thedisk, and a vertical standard, o,

screws into the latter at its centre, the vlower end of the standardterminating in two lugs o' o', between which the lower end of rod C or Cpasses, and tok which it-is fastened by a removable pin or bolt, b.

An arched dome, W, having apertures through its sides, is attached tothe upper, side of disk-M, enclosing between it and the disk aball-valve, I.

'A stem, s, projects vupward from the top of the arch orcover W, andscrews into a guide-plate, T, having suitable openings in it to let tbewater pass through.

rlhis whole apparatus, consisting of disk M, yoke n, standard o, arch W,valve I, and guide T, constitutes 1n y improved plunger, its advantageover all others -being that whileJ it runs .easily in the cylinder, andoperates i perfectly, its ball-valve not being liable to get out oforder, it can, by removing the pin b and swinging the rod (l C to oneside, be readily removed from the bottom of the cylinder for the purposeof repairing .the packing, or cleaning it, or for yany other purpose.

If' preferred, the arch YV may be cast to a ring, R, and the latter'screwed to a suitable hollow stein on the upper side oi' the diskv M, asshown in the drawing, The arch can then be detached from the disk forthe purpose of inserting or removing the ball.

Having thus described my invention, `Vl/'hat I claim as new, and desireto secure by Letters 'Pat-cnt, is V A pump-plunger, constructed oi' theguide T, valve I, ring 1t, disk M, yoke-n., and standard o o', combinedand arranged as herein described and for the purposes set forth.
